The introduction of tests recognizing 'anti-citrullinated protein antibodies' (ACPA) has caused a revolution in rheumatology. Immunization against citrullinated proteins is a feature almost unique for rheumatoid arthritis, although ACPA may occur long before the onset of symptoms. Even if the presence of ACPA does not seem to reveal a distinct arthritis phenotype at symptom onset, it predicts a...
The roles of anti-citrullinated protein antibodies in the immunopathogenesis of rheumatoid arthritis
Antibodies against citrullinated proteins are highly specific for rheumatoid arthritis (RA), but little is understood about their citrullinated target antigens. We have detected a candidate citrullinated protein by immunoblotting lysates of monocytic and granulocytic HL-60 cells treated with peptidylarginine deiminase. In an initial screen of serum samples from four patients with RA and one con...
OBJECTIVE Rheumatoid arthritis (RA) is associated with the presence of anti-citrullinated protein antibodies (ACPAs). Nearly two-thirds of patients with ACPA-positive RA have immune complexes that contain citrullinated fibrinogen, and these citrullinated fibrinogen-containing immune complexes (cFb-IC) can exacerbate disease in murine models of RA; however, the exact role of such ACPA ICs in RA ...
BACKGROUND Interstitial lung disease (ILD) is associated with high morbidity and mortality in rheumatoid arthritis (RA). Citrullinated proteins are observed in RA lung tissues; however, the association of specific anticitrullinated peptide antibodies (ACPA) with ILD in RA is unknown. METHODS RA patients underwent multidetector CT (MDCT) of the chest, from which ILD features and a semiquantita...

ABSTRACT Objectives: This study aims to analyze the distribution and clinicopathological characteristics of anti-aminoacyl-transfer ribonucleic acid (tRNA) synthetase (ARS) antibodies in rheumatoid arthritis patients. Patients and methods: We retrospectively studied the anti-ARS antibody levels in 228 RA patients’ (44 males, 184 fema...
